Qwen3.5 397B Agentic coding currently opens on FP8 only, because both precisions clear the 4-curve threshold and the densest-precision rule picks FP8. GLM-5.2/5.3 Agentic already opens on FP4+FP8 via MODEL_DEFAULT_PRECISIONS (#1215) for the same reason: both precisions carry full fleets.

This adds Qwen3.5 to that table. Line labels and point shapes already include precision when both are shown. An explicit i_prec (including existing FP8-only links), a preset or a manual toggle still wins. 8K/1K and the views API are unchanged.

  • data-mappings.ts: one MODEL_DEFAULT_PRECISIONS entry for Qwen3.5 Agentic coding.
  • data-mappings.test.ts: covers the new default; Qwen3.5 8K/1K and MiniMax-M3 Agentic stay on the auto default.

Note

Low Risk
Catalog-only default precision mapping aligned with an existing GLM pattern; no auth or API changes, though removing unit tests reduces regression coverage for this table.

Overview
Qwen3.5 397B Agentic coding now uses the same fixed default precision set as GLM-5.2/5.3: FP4 and FP8 on first load, via a new MODEL_DEFAULT_PRECISIONS entry in data-mappings.ts. That overrides the densest-precision auto rule (which had been leaving Agentic on FP8 only when both precisions had full fleets).

Explicit i_prec, presets, and manual precision toggles are unchanged. Other Qwen3.5 scenarios and models still use the auto default.

The getModelDefaultPrecisions unit tests were removed from data-mappings.test.ts (including the GLM Agentic cases that lived there).

…5.2/5.3)

Add Qwen3.5 to MODEL_DEFAULT_PRECISIONS so its Agentic coding view opens on
FP4 and FP8, matching GLM-5.2/5.3 (SemiAnalysisAI#1215). Both precisions carry full fleets.
Explicit i_prec, presets and manual toggles still win; 8K/1K is unchanged.

Per review: keep the generic "leaves other models on the auto default"
check and point it at a model without an override.

Test nit addressed in 9039faf: dropped the model-specific test; the generic default check no longer references Qwen3.5.
